The Dynabit™ line features a modest down-shear for an excellent finish. The helix bits have a spiral-like twist to the cutting edges, making them especially good on difficult materials such as melamine.
An adhesive-trapping gap between cutting edges and pilot bearing is featured on tools #47111 & #47113.
